vapour pressure

Type of information:

experimental study

Adequacy of study:

supporting study

Reliability:

2 (reliable with restrictions)

Rationale for reliability incl. deficiencies:

other: see 'Remark'

Remarks:

The value is the extrapolated value at ambient temperature based on peer-reviewed raw vapour pressure data across a broad range of temperatures. The reference source is a well-known and reliable source of critically-reviewed vapour pressure data, which cites the original source of the data.

Principles of method if other than guideline:

No details are available on the guideline used to determine this result.

GLP compliance:

not specified

Temp.:

25 °C

Vapour pressure:

0 Pa

Transition / decomposition:

no

The value at 25ºC is determined using the Antoine Equation by applying three standard coefficients for use in that equation, derived by Boublik et al. from reliable raw data.

Conclusions:

A vapour pressure value of 1.52E-04 Pa at 25ºC is reported in a collection of reliable data which has been subject to peer-review and in which the original data sources are traceable. The result is considered to be reliable.

Description of key information

The vapour pressure of a commercial sample of hexadecan-1-ol is 0.0021 mmHg (0.28 Pa; 0.003 mBar) at 38°C. It is supported by a reliable measurement of 0.0014 Pa at 25°C using a highly pure sample (Daubert and Danner, 1989), which is consistent with the trend of values for pure alcohols in the homologous series.

Key value for chemical safety assessment

Vapour pressure:

0.001 Pa

at the temperature of:

25 °C

Additional information

The vapour pressure of 0.28 Pa at 38°C was determined in a reliable study.

It is supported by a consistent and reliable measurement of 0.0014 Pa at 25°C using a highly pure sample (Daubert and Danner, 1989). A value of 1.52E-04 Pa at 25°C, taken from a reliable reference source (Boublik et al., 1984) is also available.

The quantified value at ambient temperature from Daubert and Danner is used in environmental modelling.

Discussion of trends in the Category of C6-24 linear and essentially-linear aliphatic alcohols

 

As chain length increases, vapour pressure decreases. This is because molecular weight is higher and intermolecular forces in the substance are all higher.
